Patent number: 10463446Abstract: A biopsy marking apparatus for placing a radiopaque marker at the location of a percutaneous biopsy. The biopsy marking apparatus comprises an introducer in combination with a radiopaque marker. The introducer ejects the radiopaque marker at the location of the biopsy. The introducer is configured to completely eject the radiopaque marker and prevent it from being subsequently drawn into the introducer as the introducer is removed from the biopsied tissue mass. The radiopaque marker has enhanced radiopaque characteristics and enhanced non-migration characteristics.Type: GrantFiled: September 23, 2005Date of Patent: November 5, 2019Assignee: Bard Peripheral Vascular, Inc.Inventors: Richard M. Chesbrough, Steven E. Field, Ryan L. Goosen, Jeff Zerfas, Richard E. Davis

Patent number: 9149947Abstract: An apparatus includes a drive and a blade. The drive is configured to be operatively coupled to a tubular member. The drive is configured to move the tubular member from a first location with respect to the blade to a second location with respect to the blade. The blade is configured to rotate about an outer surface of the tubular member and to cut the tubular member as the drive moves the tubular member from the first location to the second location.Type: GrantFiled: August 7, 2012Date of Patent: October 6, 2015Assignee: Boston Scientific Scimed, Inc.Inventors: Jeff Zerfas, Mohamed Fazni Abdulaziz, Ray Amos

Publication number: 20060074412Abstract: An ablation probe and method of manufacturing the ablation probe are provided. The probe comprises a probe shaft and a unibody electrode element. The unibody electrode element comprises a common electrode base located at the distal end of the shaft, and a plurality of electrode tines distally extending from the electrode base. The electrode element may be created by forming divisions (such as slits or slots) from a first end of an electrically conductive elongate member towards an opposing second end of the elongate member. Alternatively, the divisions can be formed from a first end of an electrically conductive sheet towards an opposing second end of the sheet, and then bent or rolled to form the elongate member. In either case, the common electrode base can either be separately mounted to a probe shaft, or the probe shaft can be formed from the elongate member, in which case, the electrode base will be integrated with the probe shaft as a unibody structure. The electrode tines can be optionally shaped, e.g.Type: ApplicationFiled: September 24, 2004Publication date: April 6, 2006Applicant: Scimed Life Systems, Inc.Inventors: Jeff Zerfas, Steve Pickett, James Teague, Martin Donofrio
